Question #121487

Data:

length of pendulum =l=0.5m

acceleration =g=9.8m/s²

To find:

frequency =?

length of pendulum =l=0.5m

acceleration =g=9.8m/s²

To find:

frequency =?

Expert's answer

Given data,

Length of pendulum is "l=0.5m"

Acceleration due to gravity "g=9.8m\/s^2"

Since,

"T=2\\pi\\sqrt{\\frac{l}{g}}\\\\\n\\implies \\nu=\\frac{1}{T}=\\frac{1}{2\\pi}\\sqrt{\\frac{g}{l}}"Thus,

"\\nu=\\frac{1}{2\\pi}\\sqrt{\\frac{9.8}{0.5}}=0.70Hz"
